Exactly how is it crashing, can you provide a full description or sample project? Also, do you have the full stack trace?

The assertion is happening when trying to acquire the JNIEnv which is rather surprising. It should always be present, so some way of reproducing would be nice.

Exactly how is it crashing, can you provide a full description or sample project?

There is no sample project to reproduce. The Application dose not crash when changing the parameter type from ByteArray to String. So I think the access to ByteArray is suspicious.

Also, do you have the full stack trace?

No stack trace when crashing... Only the logs described in the issue are output.

It should always be present, so some way of reproducing would be nice.

OK. I try to create sample project.
But I am not sure if it will work, so I would like to know if there is a workaround.

Sorry. I couldn't make a simple sample program.
If it is difficult to survey, you can close this issue.

Closing. Feel free to reopen if there is more information we can go after.
